# Arrivals and departures planning for [OpenDreamKit mathematical data workshop](https://opendreamkit.org/2019/08/17/WorkshopOnDataInMathematics/) and [OpenDreamKit's final reports sprint](https://opendreamkit.org/2019/08/26/FinalReportsSprint)

Cernay is 9km from the nearest train station (RER B, Saint-Rémy-les-Chevreuse). There are buses from there, but few, so we will mostly be doing car shuttles. This page is the central point of communication for organising those. Please specify here when you plan to arrive / leave and by which means of transportation. Keep an eye on the page for the planning of shuttles.

The RER B trains are now fully operating, and will take you to St-Rémy-les-Chevreuse.

[ Until August 25, due to planned works, RER B trains would stop at Orsay-Ville and replacement buses would cover the final section to Saint-Rémy-les-Chevreuse, see [RER B works](https://www.ratp.fr/travaux-manifestations/rer/b) and
[RER B blog](https://www.rerb-leblog.fr/travaux/) ]

For the math data workshop, Samuel was in charge of the shuttles: [phone].

For the final reports sprint, Nicolas is in charge of shuttles: [phone].
